I just watched half of the first one.
I don't disagree with what he says except the Amadala roll. However I enjoy the movie for everything he complains about. Yes, it is stupid. I get to spend an hour and a half enjoying being stupid and taking in the latest in the craft of Sci Fi space cinematography.
As for Amadalla, I think Portman did a very credible job of portraying the role of the character. Think, this is a young girl basically conscripted to be queen in a time of conflict, that is scary level responsability, and she managed to get that subliminal trepidation into her voice that you would expect from a girl so young put in such a position.
Now back to you tube to finish the series...
